Proof of Stake

Proof of Stake (PoS) - Security Consensus

In proof of stake, the stakeholder who will form the next block (within the blockchain) is randomly selected, proportionally to the size of the stake that they have, according to the blockchain ledger. “Proof” means having evidence that blocks of transactions are legitimate. “Stake” means the relative value held by addresses on the node. “Relative value” is all the value held by wallets on a particular node divided by total value in the system. - IOHK/Cardano Foundation
